  21
  22         * doc/gnat_ugn/gnat_and_program_execution.rst: gnatelim does not need
  23         that the main unit to be built before the call, now it computes the
  24         closure of the main unit itself.
  25         * gnat_ugn.texi: Regenerate.

  67
  68         * exp_unst.ads, exp_unst.adb (In_Synchronized_Unit): New predicate to
  69         mark subprograms that cannot be eliminated because they must be treated
  70         as reachable from outside the current unit. This includes entry bodies
  71         and protected operations.
  72
  73 2018-05-31  Ed Schonberg  <schonberg@adacore.com>
  74
  75         * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
  76         Convert all operands of the generated code to Standard.Unsigned, to
  77         prevent spurious visibility errors. This is needed when the generated
  78         expansion involves a modular index type of an array type, and the index
  79         type is not immediately visible.
  80
  81 2018-05-30  Piotr Trojanek  <trojanek@adacore.com>
  82
  83         * einfo.ads (Package_Instantiation): Update comment after a routine

  87
  88         * exp_ch11.adb (Replace_Raise_By_Goto): The transfomation is legal even
  89         if the local raise statement includes a string expression. This
  90         expression might be picked up by an outer handler or discarded, but
  91         plays no role in this transformation.
  92
  93 2018-05-30  Hristian Kirtchev  <kirtchev@adacore.com>
  94
  95         * exp_aggr.adb, exp_unst.adb, freeze.adb, libgnat/a-direct.adb: Minor
  96         reformatting.
  97
  98 2018-05-30  Ed Schonberg  <schonberg@adacore.com>
  99
 100         * exp_unst.adb (Visit_Node): Handle the semantic Procedure_To_Call
 101         field in relevant nodes: Allocate, Free, and return statements.
 102
 103 2018-05-30  Ed Schonberg  <schonberg@adacore.com>
 104
 105         * exp_unst.adb (Visit_Node): Do not traverse a Component_Association
 106         that has not been analyzed, as will be the case for a nested aggregate
 107         that is expanded into individual assignments.
 108
 109 2018-05-30  Justin Squirek  <squirek@adacore.com>
 110
 111         * aspects.adb, aspects.ads: Register new aspect.

 114         aspect similar to Aspect_Max_Queue_Length.
 115         * sem_prag.adb, sem_prag.ads (Analyze_Pragma): Register new pragma and
 116         set it to use the same processing as Pragma_Max_Queue_Length.
 117         * snames.ads-tmpl: Move definition of Name_Max_Entry_Queue_Depth so
 118         that it can be processed as a pragma in addition to a restriction and
 119         add an entry for the pragma itself.
 120
 121 2018-05-30  Ed Schonberg  <schonberg@adacore.com>
 122
 123         * freeze.adb (Freeze_Object_Declaration): A pragma Thread_Local_Storage
 124         is now legal on a variable of composite type initialized with an
 125         aggregate that is fully static and requires no elaboration code.
 126         * exp_aggr.adb (Convert_To_Positional): Recognize additional cases of
 127         nested aggregates that are compile-time static, so they can be used to
 128         initialize variables declared with Threqd_Local_Storage.
 129         * doc/gnat_rm/implementation_defined_pragmas.rst: Add documentation on
 130         Thread_Local_Storage.
 131         * gnat_rm.texi: Regenerate.
 132
 133 2018-05-30  Yannick Moy  <moy@adacore.com>
 134

 139
 140         * libgnat/a-direct.adb, libgnat/a-direct.ads (Name_Case_Equivalence):
 141         Add implementation.
 142         (Start_Search): Modify to use Start_Search_Internal
 143         (Start_Search_Internal): Add to break out an extra flag for searching
 144         case insensative due to the potential for directories within the same
 145         OS to allow different casing schemes.
 146         * sysdep.c (__gnat_name_case_equivalence): Add as a default fallback
 147         for when the more precise solution fails.
 148
 149 2018-05-30  Hristian Kirtchev  <kirtchev@adacore.com>
 150

 194         in a separate routine.
 195         (Is_Atomic_Object_Entity): New routine.
 196         (Is_Atomic_Prefix): Cleaned up.
 197         (Is_Synchronized_Object): Check that the object is atomic, or its type
 198         is atomic.
 199         (Object_Has_Atomic_Components): Removed.
 200         * sem_util.ads (Is_Atomic_Object): Reword the comment on usage.
 201         (Is_Atomic_Object_Entity): New routine.
 202
 203 2018-05-30  Ed Schonberg  <schonberg@adacore.com>
 204
 205         * sem_ch3.adb (Access_Subprogram_Declaration): The flag
 206         Needs_Activation_Record is only needed on a subprogram type, not on a
 207         pointer to such.
 208         * sem_res.adb (Resolve_Selected_Component): If the context type and the
 209         component type are anonymous access to subprograms, use the component
 210         type to obtain the proper value of Needs_Activation_Record flag for the
 211         expression.
 212
 213 2018-05-30  Eric Botcazou  <ebotcazou@adacore.com>

 216         comment about the memset case.
 217
 218 2018-05-30  Bob Duff  <duff@adacore.com>
 219
 220         * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
 221         to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
 222         We need to analyze it as part of analyzing the block, so that if the
 223         call to Element that initializes Elmt_Decl returns on the secondary
 224         stack, the block will ss_mark/ss_release. This block is inside the
 225         loop; we don't want to leak memory until the loop exits.  The purpose
 226         of analyzing Elmt_Decl first was to catch the error of modifying it,
 227         which is illegal because it's a loop parameter. The above causes us to
 228         miss that error.  Therefore, we add a flag Is_Loop_Parameter, and set
 229         it on the Element entity, so we end up with an E_Variable node with the
 230         flag set.
 231         * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
 232         * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
 233         parameter not allowed" error if Is_Loop_Parameter.
 234         * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
 235         trigger the call to Diagnose_Non_Variable_Lhs.
 236
 237 2018-05-30  Arnaud Charlet  <charlet@adacore.com>
 238
 239         * checks.adb (Apply_Scalar_Range_Check):
 240         * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
 241         range values for System.Priority in CodePeer mode since the actual
 242         target compiler may provide a wider range.
 243
 244 2018-05-30  Ed Schonberg  <schonberg@adacore.com>
 245
 246         * exp_unst.adb: Search specification of main unit as well, for
 247         unnesting.
 248
 249 2018-05-30  Ed Schonberg  <schonberg@adacore.com>
 250
 251         * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
 252         a package body that is a compilation unit may contain blocks that
 253         declare local subprograms.  In Subprogram_Unnesting Mode such
 254         subprograms must be handled as nested inside the (implicit) elaboration
 255         procedure that executes that statement part. To handle properly uplevel
 256         references we construct that subprogram explicitly, to contain blocks
 257         and inner subprograms, The statement part of the compilation unit
 258         becomes a call to this subprogram. This is only done if blocks are
 259         present in the statement list of the body.
 260
 261 2018-05-30  Bob Duff  <duff@adacore.com>
 262
 263         * exp_ch7.adb: Minor comment fix.
 264
 265 2018-05-30  Ed Schonberg  <schonberg@adacore.com>
 266
 267         * exp_unst.adb (Visit_Node): Handle properly subprogram instantiations
 268         that have no corresponding body and appear as attributes of the
 269         corresponding wrapper package declaration.
 270         (Register_Subprogram): New subprogram, used for subprogram bodies and
 271         for subprogram instantiations to enter callable entity into Subp table.
 272
 273 2018-05-30  Hristian Kirtchev  <kirtchev@adacore.com>
 274
 275         * libgnat/s-secsta.adb: Reimplement the secondary stack support.
 276         * libgnat/s-secsta.ads: Update the documentation of all routines in the
 277         public part of the package.  Reimplement the private part of the
 278         package to account for the new secondary stack structure.  Add types
 279         and subprograms for testing purposes.  Add several documentation
 280         sections.
 281
 282 2018-05-30  Hristian Kirtchev  <kirtchev@adacore.com>

 315
 316         * exp_ch7.adb (Build_Finalizer_Call): Attach to tree the reference to
 317         the finalizer procedure in the At_End handler, for use in LLVM
 318         generation.
 319
 320 2018-05-29  Javier Miranda  <miranda@adacore.com>
 321
 322         * exp_ch4.adb (Expand_N_Op_Eq, Expand_Composite_Equality): Use the new
 323         subprogram Inherits_From_Tagged_Full_View to identify more reliably
 324         untagged private types completed with a derivation of an untagged
 325         private whose full view is a tagged type.
 326         * sem_util.ads, sem_util.adb (Inherits_From_Tagged_Full_View): New
 327         subprogram.
 328         (Collect_Primitive_Operations): Handle untagged private types completed
 329         with a derivation of an untagged private type whose full view is a
 330         tagged type. In such case, collecting the list of primitives we may
 331         find two equality primitives: one associated with the untagged private
 332         and another associated with the ultimate tagged type (and we must
 333         remove from the returned list this latter one).
 334

 336
 337         * exp_unst.adb (Visit_Node): Handle statement sequences that include an

 343
 344 2018-05-29  Ed Schonberg  <schonberg@adacore.com>
 345
 346         * exp_ch6.adb (Expand_N_Subprogram_Body): Do not generate push/pop for
 347         exceptions if subprogram unnesting is in effect, because these branch
 348         nodes are relevant only in the presence of nested subprograms.
 349
 350 2018-05-29  Ed Schonberg  <schonberg@adacore.com>
 351
 352         * libgnat/s-fatgen.adb (Succ, Pred):  Raise Constraint_Error

 357
 358         * einfo.ads, einfo.adb: Clarify use of Activation_Record_Component:

 566         references, examine index expressions or associated expressions as well
 567         to record uplevel references.
 568         (Vist_Node): For function and procedure calls, if a formal is an
 569         unconstrained array and the actual is constrained, check whether bounds
 570         of actual have uplevel references.

 572 2018-05-28  Ed Schonberg  <schonberg@adacore.com>
 573
 574         * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
 575         they can appear as components of activation records.
 576         * exp_unst.adb (Visit_Node): A reference to an exception may be an
 577         uplevel reference.

 594         * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
 595         value when converting a float value to a fixed-point value. This is
 596         required for CCG because it handles fixed-point types by means of
 597         unsigned integer type variables. The range check is now performed using
 598         the integer value stored in this temporary.

 634 2018-05-28  Ed Schonberg  <schonberg@adacore.com>
 635
 636         * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
 637         when bounds of fixed type are static, to remove some spuerfluous
 638         implicit conversions and provide an accurate result when converting
 639         back and forth between the fixed point type and a floating point type.

 650         (Note_Uplevel_Ref): Likewise.  Also replace reference to deferred
 651         constant with private view so we take the address of that entity.
 652         (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
 653         any; all callers changed.  Handle N_Indexed_Component like
 654         N_Attribute_Reference.  Add N_Type_Conversion case.
 655         (Visit_Node): Indexed references can be uplevel if the type isn't
 656         static.
 657         (Unnest_Subprograms): Don't rewrite if no reference given.  If call has
 658         been relocated, set first_named pointer in original node as well.
 659
 660 2018-05-28  Ed Schonberg  <schonberg@adacore.com>
 661
 662         * exp_aggr.adb (Flatten): Copy tree of expression in a component
 663         association with a range or a set of discrete choices, rather than
 664         relocating the node. This avoids inconsistencies in the tree when
 665         handling nested subprograms with uplevel references for LLVM.

 717
 718 2018-05-28  Hristian Kirtchev  <kirtchev@adacore.com>
 719
 720         * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
 721         the declarations of single concurrent types because they fall in the
 722         category of full type and object declarations.
 723
 724 2018-05-28  Eric Botcazou  <ebotcazou@adacore.com>
 725
 726         * repinfo.adb (Compute_Max_Length): Skip _Parent component.
 727         (List_Record_Layout): Likewise.
 728
 729 2018-05-28  Ed Schonberg  <schonberg@adacore.com>
 730
 731         * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
 732         includes a call to function to which it applies. This may mean an
 733         omission of an attribute reference 'Result, in particular if the
 734         function is pqrameterless.
 735
 736 2018-05-28  Justin Squirek  <squirek@adacore.com>
 737

 740
 741 2018-05-28  Yannick Moy  <moy@adacore.com>
 742
 743         * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
 744         GNATprove mode, as the order of resolution (low then high) means that
 745         all the information is not available when resolving the low bound the
 746         first time.
 747
 748 2018-05-28  Eric Botcazou  <ebotcazou@adacore.com>
 749
 750         * repinfo.adb (List_Array_Info): Start with an explicit blank line and
 751         end with the linker section, if any.
 752         (List_Entities): Do not output the linker section for record types,
 753         array types and variables.
 754         (Print_Expr): Factor out common processing for unary operators and
 755         special values.  Adjust and reorder the various cases.
 756         (List_Object_Info): End with the linker section, if any.

 772 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
 773
 774         * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
 775         of a fixed point type and the parent is a multiplying operation,
 776         resolve the operand with its own type because the context will impose a
 777         resulting type on the result of the multiplication by means of
 778         approriate conversion.
 779
 780 2018-05-25  Hristian Kirtchev  <kirtchev@adacore.com>
 781

 783         the in-place initialization aggregate created for pragmas
 784         Initialize_Scalars or Normalize_Scalars is performed with checks
 785         suppressed.
 786
 787 2018-05-25  Arnaud Charlet  <charlet@adacore.com>
 788
 789         * exp_aggr.adb (Convert_To_Positional): Bump default for

 793         * osint.adb (No_File_Info_Cache): Update initializer.
 794
 795 2018-05-25  Javier Miranda  <miranda@adacore.com>
 796
 797         * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
 798         test when the left operand is a class-wide interface and the right
 799         operand is not a class-wide type.
 800         * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
 801         left operand.
 802
 803 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
 804
 805         * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
 806         in an others clause to prevent visibility issues with the generated
 807         loop variable.
 808         (Component_OK_For_Backend): Return false for a quantified expression.
 809         (Check_Static_Component): Ditto.
 810
 811 2018-05-25  Hristian Kirtchev  <kirtchev@adacore.com>
 812
 813         * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
 814         (SS_Allocate_Dynamic): New routine. The allocation logic is now split
 815         into three distring cases rather than in one loop which attempts to
 816         handle all three cases. This rewrite eliminates an issue where the last
 817         frame of the stack cannot be freed, thus causing the memory range of a
 818         new frame to approach the overflow point of the memory index type.
 819         Since the overflow is logically treated as a
 820         too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
 821         (SS_Allocate_Static): New routine. The routine factorizes the static
 822         secondary stack-related code from the former SS_Allocate.
 823
 824 2018-05-25  Sergey Rybin  <rybin@adacore.com>

 830
 831         * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
 832         Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
 833         is created when the proper body of the stub is analyzed.
 834         * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
 835         is the proper body of a subunit, the cloned body must be inserted in
 836         the declarative list that contains the stub.
 837
 838 2018-05-25  Justin Squirek  <squirek@adacore.com>
 839
 840         * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
 841         generate code for 6.5(8-10) so that we don't get an assertion error
 842         when dealing with an incomplete return type.
 843
 844 2018-05-25  Arnaud Charlet  <charlet@adacore.com>

 873 2018-05-25  Ed Schonberg  <schonberg@adacore.com>
 874
 875         * sem_ch12.adb (Instance_Exists): New function, subsidiary of
 876         Validate_Derived_Type_Instance, to verify that all interfaces
 877         implemented by the formal type are also implemented by the actual. The
 878         verification is complicated when an interface of the formal is declared
 879         in a generic unit and the actual is declared in an instance of it.
 880         There is currently no mechanism to relate an interface declared within
 881         a generic to the corresponding interface in an instance, so we must
 882         traverse the list of interfaces of the actual, looking for a name
 883         match, and verifying that that interface is declared in an instance.
 884
 885 2018-05-25  Piotr Trojanek  <trojanek@adacore.com>
 886
 887         * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
 888         assertions; replace function versions of Next_Formal/Next_Actual with
 889         their procedural versions (which are more concise).

 957
 958         * sem_ch13.adb (Build_Predicate_Functions): The predicate function
 959         declaration is inserted into the tree and analyzed at that point, so

2405         * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2406         formsl type corresponding to the actual fixed point type is private,
2407         because in this case there can be no suspicious arithmetic operations
2408         in the generic unless they reference a formal subprogram.  Clarify
2409         warning.
2410
2411 2018-01-11  Javier Miranda  <miranda@adacore.com>
2412
2413         * exp_util.adb (Remove_Side_Effects): No action done for functions
2414         returning class-wide types since it requires generating code using
2415         'reference and the CCG target has no secondary stack.
2416         * gnat1drv.adb: Disable building static dispatch tables when generating
2417         C code.
2418
2419 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>

2428
2429 2018-01-11  Bob Duff  <duff@adacore.com>
2430
2431         * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2432         to match what the Libadalang-based version does.
2433         * doc/gnat_ugn/about_this_guide.rst: Update reference.
2434
2435 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
2436
2437         * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2438         if it contains at least one component declaration employing a function
2439         call returning on the secondary stack.
2440
2441 2018-01-11  Yannick Moy  <moy@adacore.com>
2442
2443         * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
2444         Update description of restriction SPARK_05 with SPARK 2014.
2445         * gnat_rm.texi: Regenerate.

2453         * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
2454         sem_res.adb, sem_util.adb: Minor reformatting.
2455
2456 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
2457
2458         * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2459         has a delayed aspect which must be processed at the point the type is
2460         frozen. This mimics what is done when the predicate is provided by a
2461         source aspect.
2462
2463 2018-01-11  Doug Rupp  <rupp@adacore.com>
2464
2465         * init.c (vxworks): Add macro checks for __aarch64__.
2466
2467 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
2468
2469         * exp_util.adb (Add_Failure_Expression): New routine.
2470         (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
2471         * sem_util.adb (Is_Current_Instance): Code cleanup.
2472
2473 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
2474
2475         * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2476         Default_Sec_Stack_Size.
2477         * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2478         limit check so that the integer index does not overflow. Check the
2479         dynamic stack allocation does not cause the secondary stack pointer to
2480         overflow.
2481         (SS_Info): Align colons.
2482         (SS_Init): Cover the case when bootstraping with an old compiler that
2483         does not set Default_SS_Size.
2484
2485 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
2486
2487         * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2488         legality of an inherited operation that may require overriding, ignore
2489         primitive_wrappers that correspond to explicit operations that override
2490         an interface primitive.
2491         * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2492         operation to which the class-wide expression applies is a protected op.
2493         with a primitive_wrapper, verify that the updated inherited expression
2494         does not contain an internal call to a protected function.  This
2495         completes the implementation of AI12-0166.
2496
2497 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
2498
2499         * ali.adb: Document the remaining letters available for ALI lines.
2500         (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2501         * ali.ads: Update type With_Record. Field
2502         Implicit_With_From_Instantiation is no longer in use. Add field
2503         Implicit_With.
2504         * csinfo.adb (CSinfo): Remove the setup for attribute
2505         Implicit_With_From_Instantiation.
2506         * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2507         either implicitly or explicitly withed.
2508         (Is_Implicit_With_Clause): New routine.
2509         (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2510         confusion with the with clause attribute by the same name.
2511         (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2512         * rtsfind.adb (Maybe_Add_With): Code cleanup.
2513         * sem_ch8.adb (Present_System_Aux): Code cleanup.
2514         * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2515         for a parent unit.
2516         (Implicit_With_On_Parent): Mark the with clause as generated for a
2517         parent unit.
2518         * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2519         instantiation are no longer marked as Implicit_With_From_Instantiation
2520         because they are already marked as implicit.
2521         * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2522         which marks implicit with clauses as related to an instantiation.
2523         * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2524         (Parent_With): New routine.
2525         (Set_Implicit_With_From_Instantiation): Removed.
2526         (Set_Parent_With): New routine.
2527         * sinfo.ads: Update the documentation of attribute Implicit_With.
2528         Remove attribute Implicit_With_From_Instantiation along with
2529         occurrences in nodes.  Add attribute Parent_With along with occurrences
2530         in nodes.
2531         (Implicit_With_From_Instantiation): Removed along with pragma Inline.
2532         (Parent_With): New routine along with pragma Inline.
2533         (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
2534         (Set_Parent_With): New routine along with pragma Inline.

2537
2538         * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2539         entity when the enclosing construct is a body.
2540
2541 2018-01-11  Patrick Bernardi  <bernardi@adacore.com>
2542
2543         * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2544         Secondary_Stack_Size handling as a pragma is now generated for the
2545         corresponding aspect instead of an attribute.  Pragma expression is
2546         relocated instead of evaluated. Discriminant of the corresponding
2547         record type is referenced rather than the type discriminant.
2548         (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2549         Secondary_Stack_Size rep item checks to only look for the pragma rep.
2550         * sem_ch13.adb (Analyze_One_Aspect): Transform
2551         Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2552         because the attribute does not have visibility on a task type's
2553         discriminants when the type's definition is expanded.
2554         (Analyze_Attribute_Definition_Clause): Remove handling of
2555         Attribute_Secondary_Stack_Size.
2556         * snames.adb-tmpl, snames.ads-tmpl: Remove
2557         Attribute_Secondary_Stack_Size, no longer used.
2558
2559 2018-01-11  Justin Squirek  <squirek@adacore.com>
2560
2561         * sem_ch8.adb: Minor comment fix.
2562
2563 2018-01-11  Hristian Kirtchev  <kirtchev@adacore.com>
2564
2565         * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2566         individual action because the action may denote a complex expression,
2567         such as a case statement, which in turn may contain additional
2568         transient objects.
2569
2570 2018-01-11  Ed Schonberg  <schonberg@adacore.com>
2571
2572         * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2573         analysis on a copy of the expression with a copy of the index variable,
2574         because full expansion will rewrite construct into a loop with the
2575         original loop variable.
2576         * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2577         expression is an iterated component association. Full analysis takes
2578         place when construct is rewritten as a loop.
2579         (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2580         is not safe for in-place assignment.
2581         * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2582         entity with no homonym and no other entity in the scope.
2583
2584 2018-01-11  Justin Squirek  <squirek@adacore.com>
2585
2586         * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2587         message to be printed on the pragma argument identifier.
2588

2590
2591         * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2592         entity of the generated invariant procedure in order to construct a
2593         proper entity chain.
2594
2595 2018-01-11  Piotr Trojanek  <trojanek@adacore.com>
2596

2604         Allow E_Discriminant.

2607
2608         * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2609         for atomic access once the component size is taken into account and
2610         also do it if the component type is Atomic or Volatile_Full_Access.
2611
2612 2018-01-04  Eric Botcazou  <ebotcazou@adacore.com>
